Just curious,,,,,does anyone know when the use of Campagnolo braze-on bottom bracket cable guides started to replace the clamp on type???
>From my own sometimes foggy memory, I recall them being used in the 72-73 time period forward as the "norm" on higher quality machines.

Appreciate what others have to offer on this subject.

Thanks!
